Abstract
The utility model pertains to a pump, in particular relates to a bi-directional inflating pump, which comprises a cylinder body. On upper part of the cylinder body, an upper cover is provided. The utility model is characterized in that, at middle of the upper cover, a rotary pipe is provided. The upper end of the rotary pipe is a handle, the lower end is combined with a piston in the cylinder body. In the piston, an air intake guide chamber and an air-out guide chamber are arranged. At upper and lower part of the piston, a one-way air intake port is provided respectively. The upper air-out port is communicated with the air-out port of the handle through the axial center. In the air intake part at the upper cover, a T pipe is provided, in which two valve blocks are assembled. The lower ends of the valve blocks are connected with a directional shaft. The T pipe is communicated with the outer air intake port, the cylinder body and the directional shaft. At air intaking, the utility model takes full use of the one-way communication due to combination of a T pipe with a valve. The utility model overcomes the shortcoming associated with prior inflating pump that the air chamber cover is welded with the upper cover, is simple and convenient and sturdy.
Description
Technical field
The utility model belongs to the pump class, specifically is a kind of bidirectional inflating pump.
Background technique
Used in the market gas-filled pump is generally assembled by an atmospheric air chamber and a loam cake, and Placement is welding, and the assembling of this kind gas-filled pump is convenient, flexible inadequately, and material expensive, and cost is higher.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art, and a kind of simple in structure, easy to assembly, economical and practical bidirectional inflating pump is provided.
The technical solution of the utility model is as follows:
A kind of bidirectional inflating pump, comprise cylindrical shell, above cylindrical shell, be provided with loam cake, it is characterized in that: a tube is arranged in the middle of the loam cake, the upper end of tube is a handle, piston in lower end and the cylindrical shell combines, being provided with one at internal piston enters air guide chamber and and goes out the air guide chamber, the upper and lower of piston respectively has the suction port of a unidirectional conducting, the air outlet of top communicates with the air outlet of tube through the axle center, is provided with three-way pipe on the suction port of loam cake, two valve sheets of the inner assembling of three-way pipe, one of them valve sheet the lower end connect a reversing shaft, three-way pipe respectively with outer suction port, cylindrical shell, reversing shaft communicates.
During the utility model air inlet, make full use of the characteristics that combine unidirectional conducting of three-way pipe and valve, remedied the defective that existing gas charging valve adopts air chamber cover and loam cake welding assembly mode, simple and convenient, can freely draw, push away or rotate handle according to user's custom, easy to operate, soundness is good.
The drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is the structural representation of each component of the utility model.
